Latest Patents

One of Yoshio Shiina's latest patents is a single-component developing apparatus. This innovative device comprises a developer holding member with a peripheral surface and a power supply section that applies an AC developing bias voltage to the developer holding member. The AC developing bias voltage features a waveform with predetermined minimum and maximum values, as well as a specific period. The apparatus includes an electrostatic latent image receiving member that opposes the developer holding member across a gap of predetermined width. Additionally, a developer supplying section feeds developer to the holding member, while a developer regulating member forms a thin layer of developer on the peripheral surface. This arrangement allows the developer holding member to transport the thin layer towards the receiving member, enabling the developer to fly across the gap in accordance with the AC developing bias voltage.

Another significant patent involves a developing apparatus that includes a partition between a developing roll and a stirring chamber. This apparatus features a developing roll that carries a developing agent and a partition board arranged upright along the length of the roll. This design helps maintain uniform charged amounts of the developing agent within the apparatus, resulting in recorded images with consistent density and quality.
